SEWING-MACHINE ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 524,739, dated August21, 1894.

Application filed March 3,1894. Serial No. 502.266. (No model.)

To @ZZ whom it mayconcerm Be it known that I, WINEIELD S. SOULE, acitizen of the UnitedStates, residing at Brockton, in the county ofPlymouth and State of Massachusetts, have invented new and usefulImprovements in Sewing-Machine Attachments, of which the following is aspecification.

This is a device for enabling a sewing ma` chine to stitch top facingson boots and shoes.

The nature of the invention is fully described below, and illustrated inthe accompanying drawings, in which- Figure 1 is an end elevation of aportion of a sewing machine provided with my improved attachment. Fig. 2is a front elevation of the same, a portion of the band or top facingbeing represented as broken out. Fig. 3 is an enlarged perspective viewshowing the guide piece in position, and in operation upon a top facingor band on the inside of a gaiter boot. Fig. 4 is a detail in verticalsection, a portion of the strip or bar N being represented as brokenout. Fig. 5 is a plan of the work plate. Fig. 6 is a detail in plan ofthe adjustable loopeye between the reel and the guide piece. Fig. 7 is adetached view of the sliding guide plate between the two leaves of theguide piece.

Similar letters of reference indicate corresponding parts.

a represents the work-plate, b the head of the machine, b the arm, c thepresser bar, d the presser foot, and e the needle.

A represents a band or top facing which is to be stitched as at A to theportion A of the boot by the aid of my attachment. This band or topfacing A is wound upon a reel which consists of the circular shell Bprovided with the sides or rim B and supported by the head b, and thecircular spider or disk C of size to fit into said shell, as shown inFigs. l and 2. This shell and spider or disk are hung upon a spindle Dthreaded on its outer end at D (Fig. 2) which end projects sufficientlybeyond the spider C to allow a spiral spring f to be held against thehub G of the spider by means of the nut g, thus causing the spider to bepressed against the edges of lthe coil produced by the band A inside thereel. A set-screw g can be provided to enter the hub of the spider andset against the shaft D.

As the band A leaves the reel, it passes between the rolls E supportedin the frame E which is sustained by the reel, and a suitable register hrecords the number of yards passing from the reel. After the band A haspassed between the rolls, it passes down through a guide or loop-eye,which consists of a bracket F extending from the head b or foot of thereel and provided at its end with a grooved way F. See Figs. 2 and 6.Extending from this grooved way is a bent guidewire F", and a bent wireH of substantially the shape shown has its outer end adapted to overlapthe outer end of the wire F, while its inner end I-I is broadened andprovided with a slot H, such broadened portion lying in and beingadapted to slide in the groove in the part F. By means of a set-screw Z,the wire H is moved back and forth so as to produce, in connection withthe wire F,aloopeye adjustable t0 different widths of bands A.

From the loop-eye, the band A extends down into the guide-piece, shownin Figs. l, 2, 3, and 4. This is formed on a curve, as shown, andconsists of two parallel or concentric walls, K J, joined at their innerends by a connecting wall. In other words, the guidepiece is a platebent back upon itself horizontally, but leaving a space between its twoportions, and then bent on a curve vertically. The lower portion of thepart K of this guidepiece is adj ustably secured by a screw m to a plateL, which is provided with a slot L. This plate extends horizontally fromthe foot d across the path of the band A. This band or facing A extendsthrough the guide-piece onto the work-plate a beneath the plate L, andis held against the inner edge of the guidepiece,z`. e., against thecurved wall which connects the parts J K--by a curved guidestrip or barN within the guide-piece J K, said guiding-strip N being adjustablehorizontally, so as to be moved against the edge of the band, by meansof the screw I) which screws into the strip N and has its shoulder Pbearing against the edges of the part J next a horizontal slot Jtherein. (Figs. 2 and 4.) In order to lengthen the adj ustability of thestrip N, the part J (and the slot J is extended at J', as shown in Figs.2 and 3. An index R (Figs. 2 and 7) extends from the strip or bar Nthrough the slot J to a scale R on the outer surface of the part J ofthe guide- IOO ' A with relation to the Work-plate and guideplate.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

l. In combination, the vertically curved guide-piece consisting of thetwo parallel or concentric Walls K J joined at their inner ends by aconnecting Wall, the correspondingly curved guide-strip N adjustablehorizontally within said guide-piece, said guide-strip being providedwith the screw P and said guidepiece being provided with the slot J, thehorizontal extensions J made integral with the guide-piece, and thegage-plate S provided Withl the upturned lip S adjustably secured to thework-plate, said strip N being provided With an index R and said curvedguide-piece being provided with a scale, substantially as set forth.

2. The guide, consisting essentially of the bracket F provided With thegrooved Way F', the bent Wire F, bent overlapping Wire H provided Withthe slotted thickened end H for moving in the grooved Way, and the screwZ, substantially as set forth.
